3D-Modell","subtitle":null,"slug":"2026-18-geotiff-dem-als-3d-modell","link":"https://pretalx.news-infographics-analytics-maps.media/2026/talk/M3JKAY/","description":"Ich gebe einen kurzen Einblick, wie ich einen Open-Source-Workflow entwickelt habe, um das Copernicus-DEM für eine beliebige Region herunterzuladen und anschließend in ein 3D-druckbares Geländemodell zu konvertieren.\n\nDas [Copernicus DEM - Global and European Digital Elevation Model](https://dataspace.copernicus.eu/explore-data/data-collections/copernicus-contributing-missions/collections-description/COP-DEM) stellt weltweit ein Höhenmodell als GeoTIFF bereit, ich habe mich gefragt, wie ich für einen beliebigen Ausschnitt die GeoTIFFs herunterladen kann und basierend darauf das Höhenmodell als 3D-Modell drucken kann.\n\nIm Vortrag erkläre ich kurz meine Herangehensweise, die Auswahl der Technologien und wie ich die Skripte entwickelt habe.\n\nDer [Workflow ist open source](https://codeberg.org/stroebjo/dem-to-stl) und enthält folgende Schritte:\n\n- Download des DEMs von Copernicus mit dem HDA Client\n- GDAL basierte Shellskripte um die GeoTiffs zu mergen \u0026 croppen\n- Python Skript zum erstellen eines 3D-Modells\n- JavaScript Skript für ein Multimaterial 3MF file\n\nLicensed to the public under
